Applicability

Description

This failure occurs when a role of presentation is applied to an element whose purpose is to convey information or relationships in the content. Elements such as table, can convey information about the content contained in them via their semantic markup. The WAI-ARIA role of "presentation" on the other hand, is intended to suppress semantic information of content from the accessibility API and prevent user agents from conveying that information to the user. Use of the "presentation" role for content which should convey semantic information may prevent the user from understanding that content.

Examples

Failure Example 1:

In this example, tabular data is marked up with role=presentation. Though design layout tables can be marked up in such a way, data tables need to retain their semantic information and should therefore not be marked up with role=presentation.
